(Cl. 62-l7) 3 Claims.

This invention relates to railway refrigerator cars of the top bunkertype wherein the refrigerant is carried in containers locatedimmediately below the roof and adjacent the side walls thereof. Suchcars are provided with hatches through the roof of the car, said hatchesbeing located above the containers for access to and servicing of saidcontainers, and it is necessary, ordinarily, to equip said cars withinside carlines and purlins to support said containers and the load ofrefrigerant therein. Said cars are also provided with drip pans locatedclosely below the containers to catch the drip therefrom or the liquidfrom overow. Flues are preferably associated with or formed in part bythe side walls of the car, and the metallic sheets forming said fluesextend between the spaced metallic side wall posts, said fluesconducting cooled air from the space around the refrigerant container tothe lower part of the lading compartment. When salt is used with the iceto cause lower temperature the brine resulting from the melting ice andsalt upon contacting the side wall posts causes rapid corrosion anddisintegration and, therefore, it is the principal object of the presentinvention to provide means to prevent said brine from contacting saidposts.

Also since the vertical edges of adjacent flue sheets are joinedtogether opposite said posts, if such brine contacted said verticalseam, corrosion would be more rapid which would cause breaks in the fluesheets and consequent leakage of said brine into the car insulation sothat it would come in contact with other metallic parts of the car.

More specically the invention comprises a deector or baille associatedwith the drip pan of a refrigerator car to prevent brine from reachingsaid posts or the vertical seams f adjacent flue sheets.

Other objects and advantages of the invention will appear in thefollowing description thereof.

In the drawings:

Figure 1 is a transverse section, partly broken away, of a refrigeratorcar embodying my in- Vention.

Figure 2 is a top plan view of a portion of the outer margin of a drippan showing my improved delector applied thereto.

Figure 3 is a front elevation of the improved deilector.

The general parts of the refrigerator car shown are insulated roof 2;side walls 3; floor 4; hatches 5; refrigerant container S; side wallflues 1; foraminous iloor rack 8 .and space 9 between the rack B andfloor 4. The refrigerant container 6 is positioned directly below theroof 2 and adjacent the upper part of side wall 3. A drip pan I2 isprovided below the container 6, and an upstanding partition I4 isprovided .along the inner edge of drip pan I2. The `drip pan I2, andpartition I4, cooperate with the roof 2 and side wall 3 to form anenclosing structure around the container 6, thereby providing a coolingcompartment surrounding container 6. The side wall constructioncomprises inner 24 and outer 25 side plates, inner 2l and outer 28 sidesills, outer posts 30 extending between and secured to the outer plate25 and outer sill 28, and inner posts 3I extending between and securedto inner plate 24 and inner sill 21. A lining 33 is secured to the innersurface of the inner posts 3l and .due sheets 34 are interposed betweenthe lining 33 and the posts 3|, which ilue sheets have outwardlyprojecting panels 36 formed therein to provide the side wall flues 1.Outer edge of drip pan I2 is secured to upper edge of lining 33 andpartition I4 is secured to carlines 39, which carlines 39 extend betweenthe side walls of the car and also support containers 6.

The improved deiiector is shown at 40 and is formed from preferably asingle piece of triangularly shaped sheet metal, bent along a medialline 4I from the vertex to the base, thus forming two triangular faces42 and 43 having a common vertex 44. Flanges 45 are formed along thefree side of each triangular face 42 and 43, which flanges are securedto the upper surface of drip pan I2, as by spot welding. It will benoted in Figure 2 that the deector 40 is positioned with its baseclosely adjacent and opposite the inner wall post 3| and with the vertex44 pointing toward the center of the car.

Thus any moisture dripping upon or flowing down the inclosed drip panwill be deected in its course to opposite sides of the posts 3l, itbeing understood that there is such a deector adjacent each post. Thebase of the deector is amply wide so as to divide and direct the liquidflowing on the drip pan laterally well beyond the side posts and intothe adjacent flues 1.

Obviously the flanges 45 are not absolutely essential to the properfunctioning of the invention, but are a convenience in the applicationof the deector to the drip pan, as by spot welding.

Also it will be apparent that the deiiector may have any upwardly archedform, such as that of a hollow semicone, but it is preferred that saiddeflector have substantially triangularly shaped sides which arecontiguous along one of their edges and diverging toward their otheredges and.

having a common apex. The arching of the deiiector also is suicientlyhigh so that when, for example, the refrigerant containers are drainedof the spent brine and flushed, such large volume of liquid will also beadequately deflected and kept from contact with the car wall posts, asabove described.

The accompanying drawings illustrate the preferred form of theinvention, though it is to be understood that the inventionis notlimited tol the exact details of construction shown and described, as itis obvious that various modifica-f tions, thereof, within the scope ofthe claims, will occur to persons skilled in the art.
